MN5 (essentially Langhian, early Middle Miocene)
the identification of Alicornops simorrense and assignment of the fauna to MN5 were the subject of an exchange between Cerdeño (1999) and Mazo (1999), the latter of whom defended both interpretations

25 kg of sediment was screenwashed to obtain the microfossils
it is not clear how the macrofossils were collected
the material is in the collection of the MNCN
indeterminate lagomorph tooth fragments are also present
